Get a decision we made reviewed

How to get an independent review of a decision we’ve made.

What happens in a review?

A review is when an independent reviewer takes a fresh look at the issue.

They look at the information, eg your case file, and they get evidence from you, us and other people directly involved, and make a ruling.

Important review dates

You must apply for a review within three months of the decision date on your claim or invoice. We may accept late applications for a review where extenuating circumstances exist. For example, if your injury prevented you from being able to meet the timeframe.

Setting a date for your review

The reviewer must contact you to set a date for the review within three months from the date we received your application, unless the case is sorted out before then.

Let us know if you haven’t heard from us within a month of lodging your review application. For our contact details go to:
Contact us

Getting support for your review

You can bring someone to your review hearing to either speak on your behalf, eg your advocate, lawyer, union representative, or just someone to support you through the review, eg someone from your family/whanau.

You’ll need to make sure anybody speaking for you are made ready for the review.

Bringing your lawyer to review

If you want a lawyer to speak on your behalf you’ll need to get them ready for the review and pay them.

Let us know if you have special needs

Write on your review application or letter any special needs, eg language, religion, your lack of mobility, and any seeing or hearing problems.

Cultural support for your review

You need to write any cultural support you need on your review application or letter. This support for reviews is called ‘special arrangements’. It’s up to the reviewer to agree any special arrangements.

Special arrangements for Māori people may include:

  • holding the hearing on a marae
  • conducting the hearing in Te Reo Māori
  • conducting the hearing with some degree of Maori protocol
  • providing access to assistance from local Pae Arahi.

Special arrangements for Pacific people may include:

  • allowing family or elder support
  • conducting the hearing in the relevant Pacific language
  • holding the hearing at an appropriate community venue
  • arranging to have the hearing conducted by a specially appointed Pacific people’s reviewer.
People who can attend your review

Anyone who is directly involved can attend the review hearing, including:

  • your reviewer
  • you and/or your representative
    You don’t have to attend the hearing, but it is a good idea. You can give evidence in writing instead, or your representative can present it for you.
      • a support person (if you want one)
      • a designated representative from ACC
      • your employer and/or their representative (for work injuries)
      • witnesses or experts (if applicable).

      Review hearings are not open to the public.

      Get ready for your review hearing

      You’ll have been contacted by the reviewer within three months of us receiving your application, setting a date for your review hearing.

      You’ll need to get ready for the review:

      • If you want a representative at the hearing, eg lawyer, let them know as soon as you can, so that they have time to prepare your case.
      • If you want a witness to give evidence, you must let the reviewer and other parties know before the hearing date, and give details about what the witness’s evidence will be.
      • Present any new evidence to the reviewer and other parties at least three working days before the hearing.
      • Write down the main reasons why you disagree with our decision, to refer to during the review.
      What to do if you can’t attend the review hearing

      If you want to go to the hearing, but you can’t, eg because of an emergency:

      • contact the review support officer before the hearing to let them know that you can’t attend
      • get someone to go to the hearing for you and give your evidence in writing, or your they can present it for you
      • ask the reviewer to reschedule.

      If the reviewer decides the hearing date can’t be rescheduled, then it will continue in your absence.

      What to do if you don’t want to go ahead with the review

      We call it ‘withdraw from the review’, but what it means is that you don’t want your decision to be reviewed. If you want to withdraw, you can do it any time before the hearing without giving a reason. You must let either us or your reviewer know in writing that you’re withdrawing, and it’s also a good idea to follow-up with a phone call.

      This is what happens at the review hearing
      1. The reviewer manages the hearing, which is generally informal. All the information that was used by us to make the original decision will have been made available before the hearing. This information is confidential and can only be used for the review hearing. Each party has will have a chance to have a say and ask questions.
      2. The review hearing will be tape-recorded, to provide a record in case there are any later hearings.
      3. Anyone giving evidence may be asked to take an oath or affirmation (that’s a promise to tell the truth). Reviewers can look at a range of material relevant to your case that, which may not be considered at a more formal hearing (for example at the District Court). The reviewer will sometimes allow cross-examination of a witness.

      What happens after you’ve had your review hearing

      After the hearing, the reviewer decides whether costs can be awarded. If you want to know more about this, contact the review support officer or ask the reviewer at the hearing.

      The reviewer will write to you with their decision within 28 days of the hearing. The decision is binding on all parties involved.

      Appealing review decisions

      If you’re unhappy with the decision made at your review, some decisions can be appealed. For more information go to:
      Appeal an independent review decision

      Payment of the reviewer’s costs

      We are legally required to pay the reviewer’s costs.

      Once the reviewer has made a decision, they may award costs for expenses you have incurred for representation, eg medical reports, transport costs and other reasonable expenses associated with your review hearing. We pay these costs when awarded, remember to talk to your case owner about it.

      The maximum amount that a reviewer can award in relation to a review hearing is set out in:
      Review Costs and Appeals Regulations 2002
